Generating xkcd passwords in PHP

The famous xkcd comic tells us that the password, which consists of 4 frequently used words, is easy to remember and difficult to find.


^{Translation , original}

All current implementations of this method of generating passwords are designed for English words, which means that passwords are harder to remember in Russian. I armed myself with a frequency dictionary of the Russian language, and made a PHP library that supports the generation of passwords from several sets of words:

• English words (for example, “idea critic happy chinese”);
• Russian words (for example, "powder earth zero dress");
• transliterated Russian words (for example, “vysota razum bumazhka razmer”).

Installation using composer

{ "require": { "barzo/password-generator": "dev-master" } } 

Password generation

Passwords are generated by the static function Generator :: generate , which takes three parameters: a list of words, a password length (number of words) and a word separator. For example, generating a password from 5 transliterated words separated by a hyphen:

 $wordList = new Barzo\Password\WordList\RuTranslit(); echo Generator::generate($wordList, 5, '-'); 

The output will contain a string similar to:

  dovod-gore-sever-nomer-druzhka 

For each word list there is a synonym for a quick call:

 echo Barzo\Password\Generator::generateEn(); echo Barzo\Password\Generator::generateRuTranslit(); echo Barzo\Password\Generator::generateRu();
